TYPE-WRITER DESK.

SPECIFICATION forming part of Letters Patent No. 631,300, dated August22, 1899.

Application filed February 17, 1899. Serial No. 705,747. (No-model.)

T0 all wtont t may concern:

Be it known that I, MAGNUS J. l-IAFGAR, a citizen of the United States,and a resident of Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Type-Writer Desks, ofwhich the following is a specification and which are illustrated in theaccompanying drawings, forming a part thereof.

The invention relates to that class of desks having a movable table forsupporting the type-writer, this table being Yadapted to be swungforwardly to a suitable position for operating the machine and to beswung backwardly and downwardlyfor the purpose of storing the machinewhen not in use, a movable cover being provided for the openable portionof the desk and being so connected with the table that the latter isthrown forward when the cover is opened.

The objects of the invention are to simplify the construction and actionof desks of this character and to render them cheap and durable. Theseobjects are attained in the construction hereinafter fully described andwhich is illustrated in the accompanying drawings, in which- Figure l isa centrally-vertical transverse section of the desk when opened. Fig. 2is a similar view of the desk closed. Fig. 3 is a detail of a baradapted for attachment to the openable top and serving as the means ofat tachment thereto of the operating-links. Fig. 4 is a detail bottomplan of the table-top,'some of the parts being shown partiallyinsection, the view being taken on the line 4 4 of Fig. 2. Fig. 5 is adetail on the line 5 5 of Fig. 2. Fig. 6 is the same view as Fig. 20h alarger scale. Fig. 7 is a detail section on the line 7 '7 of Fig. 6.Fig. 8 is a detail section on the line 8 8 of Fig. 6.

The general contour of:` the desk A may be of any desired form; but itmust be provided with an opening or well, within which the type-writertable and its supporting mechanism are housed. vThe type-writer table isshown at B and the openable cover for the well of the desk at C. At D isshown a shelf extending across the well of the desk and constituting afloor for ithe cabinet within which the type-writer is housed when thedesk is closed, the table then assuming the inclined position, asrepresented in Figs. 2 and 6, its rearward end rising against the frontend of the table D and its forward end being in contact with the rail c,depending from the forward portion of the openable top C. A rod Eextends across the well of thede'sk, being in such position that thetable B rests and slides upon it. The table B is provided with shoes b,each one depending a little below each of its side edges, so as to bearupon the rod E.

The table B is supported from the side walls of the Well of the desk Aand hangs upon the pivot-pins F G, set therein. A rigid linkf is pivotedupon the pin F and is pivotally connected with the side edge of thetable B, as shown at f,the latter pin extending through a longitudinalslot f2 in the link. A rigid link g is pivotally attached to the pin Gand to the side edge of thetable B, as shown at b', this point ofattachment being nearer the rear edge of the table than the pin f'. Theside edges of the table B are preferably cutaway to accommodate thelinks f g, and the latter are attached to the table through the mediumof the strap b, which has heretofore been described as a shoe, but whichprojects backwardly a sufficient distance to carry the pins f' g', thelinks j' g entering the space between the strap l) and the table B.

f The openable cover C is supported by the rigid links H K, pi votallyattached to the cover C by means of a bar M, secured to the under facethereon and having depending lugs on m' thereon. 'lhe lower`ends of thelinks H K are pivotall y attached, respectively, to arms flf, projectinglaterally from the link f. The arm f4 is located near the lower end ofthe link f and projects backwardly therefrom. The arm f3 projectsforwardly from the linkf and is located approximately midway of itslength. For the purpose of securing better leverage the link K isprolonged beyond its point ofv attachment to the armf3, and its lowerend is connected with the link g by means of the rigid link lc'.

In opening the desk, the parts being in the position shown in Fig. 2 orFig. 6, the front of the cover C is raised, thereby swinging forward andupward the links f g and raising and throwing forward the table B, whichslides upon the rod E. The relative position of the IOO linksf g causesthe table B to assume a horizontal position, and when in this positionit comes into contact with and is stopped by a lateral arm O, projectingbackward ly from the linkf. The link H serves to guide the cover C andbrings its rearward end into Contact with the stop-block d, fixed to theshelf D, thereby furnishing a suitable support for the cover when open.

The mechanism features supportinga table and cover are partially hidfrom view by means of a plate a', secured to the side wall of the wellof the desk, and a stop-block d2 is secured to this plate, and upon itrests the cover C when closed. A beveled block b is fixed upon the tableBin such a position that as the table is brought to its forward positionthe inclined face of this block slides under the lower end of thestop-block 0.2, and by this means any accidental raising of the table Bis prevented.

The bar M is preferably provided with a slot I), through which a screw cpasses into the cover C. By this device the parts are easily adjusted toa proper position in assembling.

I claim as my inventionl. In a type-writer cabinet, the combination witha desk having a well, a table adapted to oscillate in the well, a fixedsupport for the. forward end of the table, a link, g, for pivotallycarrying the rearward end of the table and being pivotally secured tothe side of the well, an oscillating cover for the well, an arm, f,pivoted to the side of the well forward of the link g, two links, I-I,K, pivoted to the armf and supporting the cover, the forward one, K, ofsuch links being prolonged beyond the pivot securing it to the arm f,and a link connecting the lower end of the link K with the link g.

2. In a type-writer cabinet, the combination with a fable, a pair ofarms swinging from a portion of the desk, and being pivoted at different points to the side of the table, a pair of rigid links pivotallysupported by the forward one of such arms, a cover pivotally carried bysuch links, the forward link being prolonged below its point ofattachment to the arm,and a link connectingsuch prolonged end with therearward arm.

3. In combination, a desk having a well, an oscillating table, an arm,g, pivoted to the desk for supporting the rearward end of the table, aswinging arm, f, supported from the desk, an oscillating cover for thewell, a rigid link leading upwardly from lthe armf, and supporting therearward end of the cover, a lever for supporting the forward end of thecover, and pivotally attached to the arm f, a link connecting the leverbelow such pivotpoint with the arm g, and means for supporting theforward end of the table.

4. In combination, a desk having a weil, a table, the arms, f, g,swinging from the desk and carrying the table, the link, l-I, and thelever, K, pivoted to the arm f, the cover carried by the link H and thelever K, the link, 7o', and the stop, O, carried by the arm, f, allsubstantially as and for the purpose specified.

5. In atype-writer cabinet, the combination with a desk having a well, atable oscillating Within the well, and means for oscillating the table,of a stop-block secured to the side Wall of the desk, and abeveled blockfixed to the table and adapted to pass under the stopblock when thetable is in its advanced position, substantially as described and forthe purpose specified.
